Example. I had 2 spread out appointments with a very local, part time (had a day job) provider (probably 8 months in between appts). She's very hot and although I never reviewed her, she would be a a 8/9....possibly an 8/10. She hasn't been reviewed since 2010, however both times I saw her were after that. Her website is inactive and she has an ad on a site, pretty known for leaving ads up in perpetuity. Our appointments were all about mutual respect.... I treated her well & she offered extras, above her menu at no $$ mark up and refused to let me leave before I came more than once. Great sessions.

She saw that you called and did not respond to your e-mail.
Rude on her part as to not at least explain why since you formed such a great relationship.

Good pick ... she was in the medical "field" although not a nurse.... I did call from a blocked #, did not leave a message & assuming by protocol that she wouldn't pick up. I basically wanted to see if it the VM was her, a dude or a generic auto-response. If I had received either of the last 2, Move on is the right choice, obviously... But it was her. Leading me to believe, who uses their personal cell for providing?

If she isn't  Navajo what makes you think she would understand a coded voice mail ?  
   Did you leave a message on her voice mail ?
If you didn't , is  there a reason you won't leave a  message in English , with the name she  
knows you by ?  
 I prefer the telephone , I always leave a  message , if I don't receive a call back ,   I  move on .
   
If she gave you more time and extra menu without a tip , maybe you didn't give her what she was  looking for ?
 Perhaps  she married her favorite  John , and kept her number active for  GF's only  .

lol. I called to see if the # was live & if it was her's. I do speak English, with a working knowledge of Gaelic & Spanish... But you been around long enough to understand "Coded" not to blow one's spot up.... When you meet a woman at a bar do you break out into acronyms like BBBJNQNS? I know you know.  

In that case, I would be there forever.

She went down again....I said we didn't have have enough time. Told her I didn't bring any extra $$ and didn't want to take advantage of her time.... more than once, told her I didn't want her to feel uncomfortable. She was persistent.... GREAT provider..

...your emails went into her spam folder and she didn't check it before they disappeared.

If she does not respond after that, she is not interested...at this time, anyway. Let her make the next move. When I take time off, I generally have it on the first line of my auto response and my P411 in all caps, so guys know not to bother at that time, but I still provide references if someone needs one.  

Get a hobby phone.  In your next message, tell her it's your new private line.  No need to block it.  Many gals know us mainly by our numbers.  I would try again, then move on.
OK to circle back periodically but do not stalk.

my number. As others have said, some providers know hobbyists by the phone #. Also, leave specific call back information when you leave your message; something like, "OK to call me between 5 and 7 pm."

I think you're putting way too much thought into it. If she's that part time, I doubt she's checking her emails daily or even weekly.  Just because a provider doesn't reply to every email you send, it doesn't mean she's rude either. Sometimes things get lost in the shuffle.  You can imagine how many emails a girl gets when she puts semi nude pictures on the internet.

What is the matter with you people? This is P4P and both parties have freedom to move on. Some providers decides to hang it up after while for many personal reasons. Occurs very often.

It kind of sucks, but there's not much that can be done about it.

There are myriads of reasons why it could happen, and you'll never know for sure what it was.

So, move on, ever on.
